this gets the total system memory, w/o swap added in but will only parse once
o getMemUsage()
this matches what ps.c had for determineing memory usage.
o getpagesize()
method to get system page size
o getPipes()
return a vector of pipes associated with this process (thread communication, or real pipes ala IPC)
o getSockets()
return a vector of sockets associated with this process (tcp,udp,raw,stream/unix)
o getUptime()
this tells us howmany seconds the system has been running

method to get accurate symbolic links
o toString()
this get called by System.out.println(process) makes debuging eaiser.
o update()
this is a method that will update a processes information
