Character deletion

Erase character

ansi_escape.erase_character(n)

Will erase n amount of characters from the cursor to the right of the cursor.
amount defaults to 1.

Delete character

ansi_escape.delete_character(n)

Works just like erase_character(), but after deleting the characters it wil shift any remaining characters to the left of the cursor by n amount.
If n is omitted it defaults to 1. Erase in display

ansi_escape.erase_in_display(n)
#or
ansi_escape.ed(n)

Will erase in the display from the cursor.
n is the direction from the cursor to erase in and can be : forward, backward, or both. n can also be "history" which works like "both", but will also include the buffered history of the terminal. I do not reccomend using history since it is not widley supported. Erase in line

ansi_escape.erase_in_line(n)
#or
ansi_escape.el(n)

Like erase in display, but limited to one line. The n variable works the same way, minus the history option.
