.SYNOPSIS
    Return the documents for a CosmosDB database collection.
 
.DESCRIPTION
    This cmdlet will return the documents for a specified
    collection in a CosmosDB database. If an Id is specified then only
    the specified documents will be returned.
 
.PARAMETER Connection
    This is an object containing the connection information of
    the CosmosDB database that will be accessed. It should be created
    by `New-CosmosDbConnection`.
 
.PARAMETER Account
    The account name of the CosmosDB to access.
 
.PARAMETER Database
    The name of the database to access in the CosmosDB account.
 
.PARAMETER Key
    The key to be used to access this CosmosDB.
 
.PARAMETER KeyType
    The type of key that will be used to access ths CosmosDB.
 
.PARAMETER CollectionId
    This is the id of the collection to get the documents for.
 
.PARAMETER Id
    This is the id of the document to return.
 
.PARAMETER MaxItemCount
    An integer indicating the maximum number of items to be
    returned per page. Should not be set if Id is set.
 
.PARAMETER ContinuationToken
    A string token returned for queries and read-feed operations
    if there are more results to be read. Should not be set if
    Id is set.
 
.PARAMETER ConsistencyLevel
    This is the consistency level override. The override must
    be the same or weaker than the account’s configured consistency
    level. Should not be set if Id is set.
 
.PARAMETER SessionToken
    A string token used with session level consistency. Clients
    must echo the latest read value of this header during read
    requests for session consistency. Should not be set if Id is
    set.
 
.PARAMETER PartitionKeyRangeId
    The partition key range Id for reading data. Should not be set
    if Id is set.
 
.PARAMETER Query
    A SQL select query to execute to select the documents. This
    should not be specified if Id is specified.
 
.PARAMETER QueryParameters
    This is an array of key value pairs (Name, Value) that will be
    passed into the SQL Query. This should only be specified if
    Query is specified.
 
.PARAMETER QueryEnableCrossPartition
    If the collection is partitioned, this must be set to True to
    allow execution across multiple partitions. This should only
    be specified if Query is specified.
