Generates a property filter condition string for a <code>long</code> value. Creates a formatted string to use
in a filter expression that uses the specified operation to compare the property with the value, formatted as
a numeric value, as in the following example:
<p>
<code>String condition = generateFilterCondition("StellarMass", QueryComparisons.GREATER_THAN, 7000000000L);</code>
<p>
This statement sets <code>condition</code> to the following value:
<p>
<code>StellarMass gt 7000000000</code>

@param propertyName
A <code>String</code> which specifies the name of the property to compare.
@param operation
A <code>String</code> which specifies the comparison operator to use.
@param value
A <code>long</code> which specifies the value to compare with the property.
@return
A <code>String</code> which represents the formatted filter condition.
