<DD>Parses a given list of options. <p/>

   <!-- options-start -->
 Valid options are: <p/>
 
 <pre> -L &lt;learning rate&gt;
  Learning Rate for the backpropagation algorithm.
  (Value should be between 0 - 1, Default = 0.3).</pre>
 
 <pre> -M &lt;momentum&gt;
  Momentum Rate for the backpropagation algorithm.
  (Value should be between 0 - 1, Default = 0.2).</pre>
 
 <pre> -N &lt;number of epochs&gt;
  Number of epochs to train through.
  (Default = 500).</pre>
 
 <pre> -V &lt;percentage size of validation set&gt;
  Percentage size of validation set to use to terminate
  training (if this is non zero it can pre-empt num of epochs.
  (Value should be between 0 - 100, Default = 0).</pre>
 
 <pre> -S &lt;seed&gt;
  The value used to seed the random number generator
  (Value should be &gt;= 0 and and a long, Default = 0).</pre>
 
 <pre> -E &lt;threshold for number of consequetive errors&gt;
  The consequetive number of errors allowed for validation
  testing before the netwrok terminates.
  (Value should be &gt; 0, Default = 20).</pre>
 
 <pre> -G
  GUI will be opened.
  (Use this to bring up a GUI).</pre>
 
 <pre> -A
  Autocreation of the network connections will NOT be done.
  (This will be ignored if -G is NOT set)</pre>
 
 <pre> -B
  A NominalToBinary filter will NOT automatically be used.
  (Set this to not use a NominalToBinary filter).</pre>
 
 <pre> -H &lt;comma seperated numbers for nodes on each layer&gt;
  The hidden layers to be created for the network.
  (Value should be a list of comma separated Natural 
  numbers or the letters 'a' = (attribs + classes) / 2, 
  'i' = attribs, 'o' = classes, 't' = attribs .+ classes)
  for wildcard values, Default = a).</pre>
 
 <pre> -C
  Normalizing a numeric class will NOT be done.
  (Set this to not normalize the class if it's numeric).</pre>
 
 <pre> -I
  Normalizing the attributes will NOT be done.
  (Set this to not normalize the attributes).</pre>
 
 <pre> -R
  Reseting the network will NOT be allowed.
  (Set this to not allow the network to reset).</pre>
 
 <pre> -D
  Learning rate decay will occur.
  (Set this to cause the learning rate to decay).</pre>
