---------------------------------------------
DESCRIPTION
---------------------------------------------
"mclear" should clears all Visor console variables before they will be updated 
during next run of the corresponding command. It OK for all type of shortcut 
(@cX, @tX, @aX, @eX) exept shortcut for node-id variables. After "mclear" @nX 
are disappear from any statistic 
---------------------------------------------
STEPS FOR REPRODUCE
---------------------------------------------
# Start cluster
# Start visorcmd ([IGNITE_HOME]/bin/ignitevisorcmd.sh)
# Connect to the ctarted cluster (visor> open)
# Execute any tasks in it (for example, run any example from EventsExample, 
DeploymentExample, ComputeContinuousMapperExample, ComputeTaskMapExample, 
ComputeTaskSplitExample) 
# Create several alerts (visor> alert)
# Run visor "mclear" command
# Run visor "node" command
---------------------------------------------
ACTUAL RESULT
---------------------------------------------
There isn't @nX values in the first table's column:
{noformat}
visor> node
Select node from:
+==================================================================+
| # |   Node ID8(@), IP   | Up Time  | CPUs | CPU Load | Free Heap |
+==================================================================+
| 0 | 6B3E4033, 127.0.0.1 | 00:38:41 | 8    | 0.20 %   | 97.00 %   |
| 1 | 0A0D6989, 127.0.0.1 | 00:38:22 | 8    | 0.17 %   | 97.00 %   |
| 2 | 0941E33F, 127.0.0.1 | 00:35:46 | 8    | 0.23 %   | 97.00 %   |
+------------------------------------------------------------------+
{noformat}
---------------------------------------------
EXPECTED RESULT
---------------------------------------------
There is @nX values in the first table's column:
{noformat}
visor> node
Select node from:
+=======================================================================+
| # |     Node ID8(@), IP      | Up Time  | CPUs | CPU Load | Free Heap |
+=======================================================================+
| 0 | 6B3E4033(@n0), 127.0.0.1 | 00:38:13 | 8    | 0.23 %   | 97.00 %   |
| 1 | 0A0D6989(@n1), 127.0.0.1 | 00:37:54 | 8    | 0.27 %   | 97.00 %   |
| 2 | 0941E33F(@n2), 127.0.0.1 | 00:35:18 | 8    | 0.20 %   | 97.00 %   |
+-----------------------------------------------------------------------+
{noformat}

"mclear" should get effect only for "mget @nX" command (with result "Missing 
variable with name: '@nX'") and @ variables  should get new values after "node" 
(or "tasks") command.Like in case for all others @ variables (@cX, @tX, @aX, 
@eX)
