Ben Greear d824eb2e66 Fix perl use of 'use lib' 
The 'use lib' logic happens in the pre-compile stage, so one cannot
use normal 'if' logic to use a particular INC.  Instead, just make sure
that best dir is added to 'use lib' last since it prepends to INC.

Below is an example of a set_script for script name bunny
set_script hunt-sta-A bunny 4096 ScriptHunt '60000 1000 50000,100000,500000,20,56000,30000,1,100000, 60,128,256,512,1024,1280,1460,1472,1514 60,128,256,512,1024,1280,1460,1472,1514 100,300,400,600,800,955 NONE' ALL 0
which should follow this syntax:
endp: hunt-sta-A
name: bunny
flags: 4096
type: ScriptHunt
private: '60000 1000 50000,100000,500000,20,56000,30000,1,100000, 60,128,256,512,1024,1280,1460,1472,1514 60,128,256,512,1024,1280,1460,1472,1514 100,300,400,600,800,955 NONE'
group_action: ALL
loop_count: 0
The private syntax is very opaque
ScriptHunt syntax is: run_duration pause_duration constraints payload_sizes_a payload_sizes_b attenuations attenuator
run_duration 60000
pause_duration 1000
constraints 50000,100000,500000,20,56000,30000,1,100000,

[--action { set_script|start_cx|quiece_cx|stop_cx|show_report|del_script } ]
set_script: configure a cx with script parameters set in script_type, script_flags
show_port: show script report for cx
del_script: remove script from cx
start_cx: start traffic on a connection (thus starting script)
quiece_cx: stop transmitting traffic and wait a period before stopping connection recieve
stop_cx: stop transmit and recieve immediately

[--endp_name {endpoint name}]

[--script_type {2544|Hunt|WanLink|Atten} ]
2544 - RFC 2544 type script
Hunt - Hunt for maximum speed with constraints
WanLink - iterate thru wanlink settings
Atten - use with attenuators
[--flags - see LF CLI User Guide script flags for set_port]
[--script_name - script name]
[--loops - how many time to loop before stopping; (0 is infinite)]
[--private - the nested script-type parameters in a single string]
[--log_cli {1|filename}]
