simple calculator language in progress for expansion

EQ works just like a normal calculator with the additional features of vectors, variables and functions.

Vectors are defined like this: [1 2 3] This vector contains the numbers 1, 2, 3. Binary and unary operations work like this:

[1 2 3] + 1         ->  [2 3 4]
[1 2 3] - 1         ->  [0 1 2]
[1 2 3] + [3 2 1]   ->  [4 4 4]

[1 2 3] # 0         ->  1
[1 2 3] # 1         ->  2
[1 2 3] # 2         ->  3

Variables are defined like this: x : 1 + 2 x now contains the number 3.

Functions are defined like variables but with parameters: f(x) : x * 2 This function will double what ever value is put into it.
