Code for enhancements

[bflorac]

I have implemented the following enhancements:

• Increased size of the Power10 array to 51 elements to allow for additional leading zeros without loosing precision.
• When converting from float to string, the resulting string should always have a decimal point. (ie: 2.0)
• Added Rename and Insert functions (with various overloads)
• Added support for escapes in strings (ie: "front\back")
• Added support for nested arrays in paths (ie: myarray[0][0])
  If you want them, let me know how to best post them.
