Many of the UPM libraries allocate space on the heap but do not explicitly handle copying and assignment. This commit uses C++11 delete to forbit both the copy and assignment operator for these classes. The C++ examples which used assignment operators to initialize class instances were also updated since it did not appear necessary in those cases to use the assignment operator.

* @brief API for the Water Flow Sensor
|
|
*
|
|
* This sensor is used to measure water flow in liters per
|
|
* minute (LPM). It incorporates a Hall Effect sensor. The UPM module
|
|
* defines an interrupt routine to be triggered on each low pulse,
|
|
* keeping count. This device requires a 10K pull-up resistor for
|
|
* the signal line (yellow wire). There is a schematic diagram on
|
|
* the SeeedStudio site (3/2015):
|
|
* http://www.seeedstudio.com/wiki/index.php?title=G1/2_Water_Flow_sensor
|
|
*
|
|
* However, be careful when wiring this up - the schematic appears to
|
|
* have a bug in it: the lower left connection of the signal line
|
|
* (yellow) to Vcc (red) should not be there. The sensor can work
|
|
* with this connection, but probably not for very long.
