title: Read text file into string array (and write)
body: <p>The ability to read (and write) a text file into and out of a string array is I believe a fairly common requirement. It is also quite useful when starting with a language removing the need initially to access a database. Does one exist in Golang?<br>
  e.g. </p>
  
  <pre><code>func ReadLines(sFileName string, iMinLines int) ([]string, bool) {
  </code></pre>
  
  <p>and   </p>
  
  <pre><code>func WriteLines(saBuff[]string, sFilename string) (bool) { 
  </code></pre>
  
  <p>I would prefer to use an existing one rather than duplicate.</p>
