> StringGroovyMethods has many issue: 
> 1) Inefficient converting CharSequence  to String. If do not convert, the method of CharSequence wiil twice faster.
> 2) IOGroovyMethods.readLines is slow, do not use it. readLines use a closue!
> 3) the methods of center/denormalize/expand/pad/strip are Inefficient, there is no need creat so many StringBuilders
> I'll fix this (on github) in a few days. Please help me check and merge it.
