tablol. This is a project to implement something like "excel" but -= 10000, however it is just for funny, the idea was taken from a Tsoding video. The idea was successfully implemented, so the program is able to do arithmetic operations, cells cloning and error reporting. Errors: * num_defintion: Wrong number defintion (Maybe..?). * empty_cell: The current cell has not any tokens. * loop_dependecy: A loop between cells occured. * outta_range: Trying to clone a cell that doesn't exist. * missing_args: Ain't operands nor operators enough to perform any arithmetic operation. Clone method: To be able to clone a cell the syntaxis must look like: @<column><row> where column is a serie of upper-case letters and row is the row number (The orden does not matter).
