[] Operation
  Matrix or string access operation. In a matrix, can be used to access any given element, indexed by row and column position.
Syntax  Matrices: Matrix_Ident[row][column];
Strings: String_Ident[position];
or
String_Ident[start_index][end_index];
Notes
For strings, the [] operation returns the character at a given position in the string (indexed from 0). []can also be used to generate a substring of a given string.

Indexing starts at 0. For row or column vectors single index will suffice, i.e. v[0][2] is the same as v[2] if v is a row vector.

Examples
test_string = "Hello cruel world";
test_substring = test_string[0][4]; // "Hello"
