Implement the full set of mathematical operations for number types

[Isaac-Leonard]

Currently I've not focused on adding operations for some of the number types unless directly needed as I have been focused on more complicated parts of the compiler.
These operations however will be needed for actually writing programs eventually.
If anyone would like to help contribute this should be a relatively easy spot to begin.
Some of the symbols such as >> and << for bit shifting will need to be added to the parser.
Type checking and transformations will need to be added to the ast and the code in share.rs and the actual machine instructions will need to be implemented in the compiler.
Any help would be appreciated.
