                       LineStart

Matches if current position is at the beginning of a line within the parse string

Example:

   test = '''\
   AAA this line
   AAA and this line
     AAA but not this one
   B AAA and definitely not this one
   '''

   for t in (LineStart() + 'AAA' + restOfLine).searchString(test):
       print(t)

prints:

   ['AAA', ' this line']
   ['AAA', ' and this line']
