text: Parsing a String
  First thing is first we want to read in a file. I won't be writing full compiling examples as I'm usually doing this on my phone. However, in general any examples can be pasted directly into a main function because D has nested everything.
  void main() { import std.file; auto data = readText("filename.ext"); }
  readText reads the entire file into memory. Usually not a bad start but could be a problem with very large files. D also utilizes immutable strings, so techniques I'm showing generally do not use additional memory.
  Matching Beginning or End
  Sometimes all that is needed is a check if the beginning or end matches a value.
  import std.algorithm; auto data = "word word" assert(data.startsWith("word")); assert(data.endsWith("word")); assert(data.skipOver("word")); assert(data == " word");
  skipOver will not only identify if the string is found at the beginning, but also move data past the string.
  Removing Whitespace
  import std.string; auto data = " str "; assert(data.strip == "str"); assert(data.stripLeft == " str"); assert(data.stripRight == "str ");
  Along with whitespace an argument can be past in to specify a specific string to strip off.
  Find a String
  Rather than reiterate here, see my previous post. I also am preparing the next post which dives into more of the variations.
  Regular Expressions
  The standard regex library is very nice. I won't be going over examples because regular expressions themselves are a more advanced topic.
