Concatenates the current string with the string passed as parameter.

Example:

'Flavio'.concat(' ').concat('Copes') //'Flavio Copes'

You can specify a variable number of arguments, and if you do so all those arguments will be concatenated to the original string:

'Flavio'.concat(' ', 'Copes') //'Flavio Copes'
