 The new model is much simpler since we only need lshw. There is a parent class called Component that defines a poll method. Each component should be able to poll for it's data, however the flag (to define what information to get from lshw) and the regexp are uninitialized arguments (no defaults so ther is much bitter complainting if I forget one, by design).  I use popen3 to call lshw. This suppresses any extraneous output lshw makes. I also scan std error and raise and exception if I lshw is not found (it's a configurable parameter). Component should not be instantiate-able, instead all other datum should be derived from it, and then provide named accessors to the derived components.

+After trying to build the network class I realized that the common set of things that need to be done by each child does NOT involve searching. Meaning that each child will have to "scrape" the lines a little diffrently. However each child does need to run lshw, and should require it to spit out an 
+array of lines or a "folded" array of lines where each fold occurs at a marker, typically the marker is *-, this is the default method of output. In version 2.08 onward I've replaced the collection of functions in Component(the parent) with a single function, lshw_arr which takes a flag (for the -c argument) and an optional marker. If the marker is specfied I use Array.search and Array.map to fold the array, other wise I just return it straight. All elements of the array are .strip(ed) and .flatten.compacted(ed) to ensure sanity of the return values. I don't want to pass around nested arrays. If something needs nesting I'll make it a new object, but return values should have at most 1 level of nesting.
