** Added
Added write to lisp
Added Cell Compactor to Lisp garbage collector resulting with multiple performance improvements
Added bootstrapping steps documentation
Added ability to specify amount of Available RAM on a Per run basis, however 16KB is the default

** Changed
Correct lisp High level prototype to include line comments
Changed default RAM to 16KB
Updated bootstrap documentation to match the memory requirements of the individual steps

** Fixed
Fixed missing traces when memory outside of world are accessed when profiling
Imported improved High Level Lisp Prototype

** Removed

* 0.0.4 - 2017-02-18
** Added
+ Added missing primitives from High level prototype to lisp implementation
+ Improved Eval's debugging messages

** Changed
+ Readline function no longer displays EOF Char should the user terminate input with Ctrl-d

** Fixed
+ Corrected Eval's processing of ASCII type

+ Properly display Integer Cells with the value of ZERO

** Removed
+ Removed Eval's default behavior of unknown input

* 0.0.3 - 2017-02-17
** Added
+ Added a primitive Lisp implementation in assembly
+ Gave primitive Lisp an exact garbage collector for CELLs (aka everything but strings)
+ Added a concatination program to make dealing with line macros easier for M0-macro programmers
