/**
* Defines (or modifies) an object property.
*
* ## Notes
*
* -   Property descriptors come in two flavors: **data descriptors** and **accessor descriptors**. A data descriptor is a property that has a value, which may or may not be writable. An accessor descriptor is a property described by a getter-setter function pair. A descriptor must be one of these two flavors and cannot be both.
*
* @name defineProperty
* @type {Function}
* @param {Object} obj - object on which to define the property
* @param {(string|symbol)} prop - property name
* @param {Object} descriptor - property descriptor
* @param {boolean} [descriptor.configurable=false] - boolean indicating if property descriptor can be changed and if the property can be deleted from the provided object
* @param {boolean} [descriptor.enumerable=false] - boolean indicating if the property shows up when enumerating object properties
* @param {boolean} [descriptor.writable=false] - boolean indicating if the value associated with the property can be changed with an assignment operator
* @param {*} [descriptor.value] - property value
* @param {(Function|void)} [descriptor.get=undefined] - function which serves as a getter for the property, or, if no getter, undefined. When the property is accessed, a getter function is called without arguments and with the `this` context set to the object through which the property is accessed (which may not be the object on which the property is defined due to inheritance). The return value will be used as the property value.
* @param {(Function|void)} [descriptor.set=undefined] - function which serves as a setter for the property, or, if no setter, undefined. When assigning a property value, a setter function is called with one argument (the value being assigned to the property) and with the `this` context set to the object through which the property is assigned.
* @throws {TypeError} first argument must be an object
* @throws {TypeError} third argument must be an object
* @throws {Error} property descriptor cannot have both a value and a setter and/or getter
* @returns {Object} object with added property
*
* @example
* var obj = {};
*
* defineProperty( obj, 'foo', {
*     'value': 'bar'
* });
*
* var str = obj.foo;
* // returns 'bar'

*
* -   Property descriptors come in two flavors: **data descriptors** and **accessor descriptors**. A data descriptor is a property that has a value, which may or may not be writable. An accessor descriptor is a property described by a getter-setter function pair. A descriptor must be one of these two flavors and cannot be both.
*
* @param {Object} obj - object on which to define the property
* @param {string} prop - property name
* @param {Object} descriptor - property descriptor
* @param {boolean} [descriptor.configurable=false] - boolean indicating if property descriptor can be changed and if the property can be deleted from the provided object
* @param {boolean} [descriptor.enumerable=false] - boolean indicating if the property shows up when enumerating object properties
* @param {boolean} [descriptor.writable=false] - boolean indicating if the value associated with the property can be changed with an assignment operator
* @param {*} [descriptor.value] - property value
* @param {(Function|void)} [descriptor.get=undefined] - function which serves as a getter for the property, or, if no getter, undefined. When the property is accessed, a getter function is called without arguments and with the `this` context set to the object through which the property is accessed (which may not be the object on which the property is defined due to inheritance). The return value will be used as the property value.
* @param {(Function|void)} [descriptor.set=undefined] - function which serves as a setter for the property, or, if no setter, undefined. When assigning a property value, a setter function is called with one argument (the value being assigned to the property) and with the `this` context set to the object through which the property is assigned.
* @throws {TypeError} first argument must be an object
* @throws {TypeError} third argument must be an object
* @throws {Error} property descriptor cannot have both a value and a setter and/or getter
* @returns {Object} object with added property

/**
* Generates a pseudorandom integer on the interval \\( [1,2^{31}-1) \\).
*
* ## Method
*
* Linear congruential generators (LCGs) use the recurrence relation
*
* ```tex
* X_{n+1} = ( a \cdot X_n + c ) \operatorname{mod}(m)
* ```
*
* where the modulus \\( m \\) is a prime number or power of a prime number and \\( a \\) is a primitive root modulo \\( m \\).
*
* <!-- <note> -->
*
* For an LCG to be a Lehmer RNG, the seed \\( X_0 \\) must be coprime to \\( m \\).
*
* <!-- </note> -->
*
* In this implementation, the constants \\( a \\), \\( c \\), and \\( m \\) have the values
*
* ```tex
* \begin{align*}
* a &= 7^5 = 16807 \\
* c &= 0 \\
* m &= 2^{31} - 1 = 2147483647
* \end{align*}
* ```
*
* <!-- <note> -->
*
* The constant \\( m \\) is a Mersenne prime (modulo \\(31\\)).
*
* <!-- </note> -->
*
* <!-- <note> -->
*
* The constant \\( a \\) is a primitive root (modulo \\(31\\)).
*
* <!-- </note> -->
*
* Accordingly, the maximum possible product is
*
* ```tex
* 16807 \cdot (m - 1) \approx 2^{46}
* ```
*
* The values for \\( a \\), \\( c \\), and \\( m \\) are taken from Park and Miller, "Random Number Generators: Good Ones Are Hard To Find". Park's and Miller's article is also the basis for a recipe in the second edition of _Numerical Recipes in C_.
*
*
* ## Notes
*
* -   The generator has a period of approximately \\(2.1\mbox{e}9\\) (see [Numerical Recipes in C, 2nd Edition](#references), p. 279).
*
*
* ## References
