Returns a list of inventory transaction types configured in the system, optionally filtered by the criteria provided in `paramsDict`. 
Transaction types classify inventory movements (e.g. receipts, issues, adjustments) and determine whether a transaction increases or decreases on-hand quantity via the `quantitySign` attribute. 
When no filters are supplied, all inventory transaction type records are returned.

### Parameters
**paramsDict** `Dictionary`<br />
<table class='dictionaryKeyTable'>
	<tbody>
 	<tr><td> - inventoryTransactionTypeId</td><td>Integer</td><td></td></tr>	
 	<tr><td> - quantitySign</td><td>String</td><td></td></tr>	
 	<tr><td> - transactionTypeCode</td><td>String</td><td></td></tr>	
 	<tr><td> - transactionTypeName</td><td>String</td><td></td></tr>	
	</tbody>
</table>

### Returns
**data** `pyDataset`<br />

### Example
```python
# Look up all inventory transaction types that decrease on-hand quantity (e.g. issues/consumption)
paramsDict = {'quantitySign': '-'}

data = system.kanoa.inventory.getInventoryTransactionTypes(paramsDict)
data = system.kanoa.utilities.convertDatasetToJSON(data)

for i, row in enumerate(data):
	print 'Row %i'%i
	for k,v in row.items():
		print k,v
	
	break	#Just limiting to returning the columns from the first record for display purposes
>>>
Row 0
transactionTypeCode CYCLE_COUNT
quantitySign 0
transactionTypeName Cycle count adjustment
inventoryTransactionTypeId 8
>>> 
```
