Create a function called "CreateFromDescription" that takes a single string parameter as input (called "descrip"). A well-formed description *should* be in the following format (no quotes):

"Channel Operation [StartEvent - EndEvent]"

The function should parse the description into 4 separate string: Channel, Operation, StartEvent, and EndEvent. The function should print to the screen each with a label:
Channel: Channel
Operation: Operation
Start Event: StartEvent
End Event: EndEvent

Things to Note:
-3 of the substrings (Channel, StartEvent, and EndEvent) may or may not contain spaces (see examples below). Operation will never contain spaces.
-Users/Callers of this function might call the function with a malformed description The function should validate the input by ensuring the descrip parameter adheres to the above well-formed format of a description (and print an error message if it does not).

Well-Formed Description Examples:
Crown Temp Max [Start Of Weld - End Of Weld]
Weld Shear Angle Target Min [Start Of Weld - Welding]

Malformed Desciption Examples:
Hello World
Crown Temp Max [Start Of Weld - End Of Weld
Crown Temp Max [Start Of Weld End Of Weld]
Crown Temp Start Of Weld End Of Weld]
