All samples that deploy Go chaincode must now vendor
their dependencies before deployment, due to changes
in FAB-5177 which stop the shim being available at
deployment time. This CR adds the command:
"GO111MODULE=on go mod vendor"
... to all scripts/readmes as appropriate.

Rename the abstore node directory as the sample code
within is JavaScript, and we are planning to add a
TypeScript version as well.
This change also requires updates to BYFN to reflect
the renamed directory.

This change is to add a delStandard() function to the
high-throughput fabric sample, as well as fix a typo
in putStandard(). In addition to modifying the
chaincode, an additional bash script,
'del-traditional.sh', was created to remotely delete
a created asset from within the docker CLI in
accordance with the sample walkthrough.
This change is necessary to demonstrate the full
capability of the fabric Shim library, such that no
assets remain on the ledger that the user doesn't want
This change was tested on a local deployment of
Fabric 1.4, using the 'Basic Network' asset that
was created by Ethan Fox for internal use by the
IBM Blockchain Innovation Unit within GBS Global.

fabric-samples/high-throughput is a sample Chaincode for
delta-based transaction model. When executing `update`, a new delta
for a particular variable is updated to the ledger. The sum of a
variable is updated to ledger by deleting all of its delta rows
while computing the sum. The current Chaincode has two types of
pruning functions. However, there is no difference in terms of
Fabric's transaction model.
This CR adds the following changes.
- Remove unnecessary `pruneSafe` function.
- Change the name of function from `pruneFast` to `prune`.
- Update or delete related scripts.
- Improve a related documentation.

Changed README.md to instruct user to edit byfn.sh instead
of docker-compose-cli file since this is where the standard
BFYN script is now run.
Also added missing Copyright notices.

A new data storage model was implemented in the fabric-samples which allows
for high-throughput of transactions. The storage model is based on storing
deltas of a value, creating a new row for each transaction, and then merging
these deltas when the final value of the variable is required.
This concept is similar to simple integer-based CRDTs, where add or subtract
updates are constantly sent to the ledger and the merge function combines all
of these deltas into one value.
