run code: if variable match

[hchiam]

a = 1
if 1 equals a
say hi

should output

"hi"

see #9

[hchiam]

Rename these as 2 variables: isAfterIf[1] === isAfterIf[2]
Process those 2 variables like so: codeVariables.includes(variableName)
And fill local hashtable: variableValues = {}; // e.g. {a:1,b:2}
