2020-02-24: Version 0.1.1.0
--------------------------------------


- Fix multi-param datatype constructors
- Fix throwing exceptions
- Fix the use of some JS specific features in CodeGen:

  PS codegen uses JS tricks like `"a" + ["b", "c"] == "ab,c"`,
  we change the generated code like `throw new Error("a" + ["b", "c"])`
  to `throw Error("a" + ",".join(["b", "c"]))`.
  
  \*Further optimizations can be done later.

---------------------------------

0. codegen behavior: add default value `None` for each function argument. fix #10
1. faster codegen: avoid pretty print when not specified. #13
2. lighter volume: for generated files. type level computing can produce huge amount of code, to make generated code Git maintainable, we use bzip2 to compress stuffs. #13
3. options for pspy-blueprint changed.

---------------------------------
