DESCRIPTION
Mount Client is a simple example of a PySimpleClient which inquires manager
about what components are currently available and then plays with 
one of a <a href="../../idl/html/interfaceMOUNT_ACS_1_1Mount.html">Mount</a> components
BACI properties.

WHAT CAN I GAIN FROM THIS EXAMPLE?
- PySimpleClient usage.
- Using manager to dynamically determine what components are available.
- Accessing (remote) components.
- Manipulating BACI properties

# Import the acspy.PySimpleClient class

# Print information about the available COBs

simpleClient.getLogger().logInfo("COBs available are: ")

# Do something on a device.
simpleClient.getLogger().logInfo("We can directly manipulate a device once we get it, which is easy.")
